Peculiarities of metals uptake by the biofuel crop Miscanthus x giganteus were explored during plant growth at
soil from the military site (Sliač, Slovakia). The experiment was carried out in greenhouse during two vegetation
seasons. Research soil was predominantly elevated in Fe and Ti, while other metals (As, Cu, Mn, Sr, Zn and Zr)
were presented at order of magnitude lower concentrations. No inhibition of plant growth was observed. The calculated
Bioconcentration Factor showed that levels of metals’ accumulation by plant roots, stems and leaves were
independent of metals’ concentrations in the soil. The accumulation of metals by stems and leaves was much lower
than by roots. As, Zr, Ti were almost not accumulated by stems and leaves during both seasons; accumulation of
Cu, Fe, Mn, Zn and Sr was not essential which confi rmed that biomass of M. x giganteus might be processed for
the energy purpose.
